Abstract
Description
- This invention is related to the field of metal cutting tools and, more specifically, to the field of milling cutters. Most specifically, this invention has application to a very special type of milling cutter especially useful in cutting sprockets.
- As is known in the prior art, a sprocket cutter has a number of stations at which there are means for cutting the contour of a sprocket. The cutting means is typically a number of cutter buttons or round inserts with their cutting edges arranged in the shape of the sprocket contour. The inserts at each station are slightly displaced parallel to the axis of rotation from the inserts at every other station. In this way, a complete revolution will cause the entire sprocket contour to be contacted by the cutting edges of the inserts.
- In the past, the inserts have been attached directly to the cutter body by means of screws or similar fastening means in conjunction with a hole in the center of the insert. See, for example, United States Patent No. 3,540,103. A problem with this type of fastening means is that during use, the insert may wobble slightly, or even loosen, thereby causing loss of tolerance.
- It is thus desirable to have an insert that will not loosen during use.
- Another problem with the prior art is that, if the insert should break or become dislodged, the cutter body itself may be exposed to the workpiece. This can cause damage to the cutter body, a very expensive piece of equipment.
- It is thus desirable to prevent damage to the cutter body.
- Thus, it is an object of this invention to have a sprocket cutter in which the cutting inserts are rigidly held.
- It is another object to have a sprocket cutter in which the inserts are resistant to loosening.
- It is a further object to have a sprocket cutter in which the cutter body is prevented from damage due to a broken or dislodged cutting insert.
- It is a still further object to have a sprocket cutter that will cut an accurate contour over long periods of use.
- According to the invention, disclosed is a sprocket cutter comprising a cutter body having a plurality of wedge recesses facing the periphery within each pocket. An array of inserts is disposed within each of the pockets, each of the inserts having a cutting portion. There is also a plurality of wedges equal in number to the number of inserts and wedge recesses. Each of the wedges is interposed between each of the inserts and each of the wedge recesses so that as each of the wedges is moved inwardly into its corresponding wedge recess, each of the inserts is securely clamped between its corresponding wedge and the pocket. Each of the inserts is positioned so that the cutting portion of each insert extends beyond the periphery of the cutter body. Each of the inserts cuts a segment of the sprocket contour as the cutter body rotates with adjacent segments of the sprocket contour being cut by inserts located in different pockets.
- The sprocket cutter further comprises a plurality of cartridges corresponding to the number of cutter body pockets for insertion into each of the pockets. Each of the cartridges has an insert receiving portion and a rear portion. The cartridges are interposed in each pocket between the arrays of inserts and the pocket so that each of the inserts abuts the insert receiving portion and is securely clamped thereon by the wedges.
- Preferably, the insert receiving portion comprises a plurality of insert seating positions equal in number to the number of inserts in the array of inserts. Each of the insert seating positions has a V-shaped surface for accurately receiving and locating each of the inserts.
- Preferably, also, the insert receiving portion further comprises a shim recess and shim located rearwardly in the rotational sense from each of the insert seating positions so that the bottom of each of the inserts will abut the top of each of the shims.
- Preferably, each of the pockets has a pair of locating surfaces abutting with a pair of locating surfaces on the rear portion of each of the cartridges. The pocket locating surfaces and the cartridge locating surfaces similarly converge toward the periphery of the cutter body.
- It is most preferable that each of the wedges has a flat bearing surface for engagement with each of the inserts and a rounded surface opposite the flat bearing surface for engagement with a similarly rounded surface of the wedge recess.
- Each of the pockets has a chip gash portion forward in the rotational sense of the array of inserts. The radius of the cutter body is reduced at each of the chip gash portions.
- It is most preferable that each of the inserts is round.
- According to the invention, there is also disclosed a cutter cartridge having an insert receiving portion and a rear portion. The insert receiving portion has a plurality of insert seating positions, each of which has a V-shaped surface for accurately receiving and locating a cutting insert.
- It is preferable that the insert receiving portion 'also have a shim recess arid shim located rearwardly in the rotational sense from each of the insert seating positions. It is also preferable that the rear portion of the cartridge has a pair of locating surfaces converging toward the insert receiving portion of the cartridge.
- According to the invention, there is disclosed a method of assembling a sprocket cutter of the type having a cutter body having a plurality of pockets and wedge recesses, a plurality of cartridges equal in number to the number of pockets and having a rear portion, a plurality of insert seating positions and shim recesses both equal in number to the number of wedge recesses, and a plurality of wedges equal in number to the number of wedge recesses. The method comprises inserting a cartridge into a pocket of the cutter body and causing the two locating surfaces on the rear portion of the cartridge to abut two similar locating surfaces in the pocket, each of the two locating surfaces converging toward the periphery of the cutter body. A shim is located into each shim recess of the cartridge such that the shim protrudes slightly above the shim recess. An insert is then placed into each insert seating position and on top of each shim and each insert is then located with respect to a V-shaped locating surface at the rear of each insert seating position. The method further comprises interposing a wedge between each insert and each wedge recess such that, upon moving each wedge inwardly, each insert will be securely clamped. Each step of the method is repeated a number of times equal to the number of pockets in the cutter body.
- The exact nature of the present invention will become more clearly apparent upon reference to the following detailed specification taken in connection with the accompanying drawings in which:
- Figure 1 is a side view of a cutter body showing one pocket.
- Figure 2 is an enlarged view of the pocket in Figure 1.
- Figure 3 is a view of the pocket of Figure 2 with a cartridge but showing only one insert and one wedge.
- Figure 4 is a view from the left of Figure 3 showing a cartridge with a full array of inserts and corresponding wedges.
- Figure 5 is a view taken along the line V-V of Figure 4.
- Figure 6 is a view taken along the line VI-VI of Figure 5.
- Figure 7 is a partial view of the station shown in Figure 5.
- Referring to the drawings more in detail, Figure 1 illustrates the
cutter body 2 with only one pocket 4 shown. In this invention, there are preferably 14 such pockets, but there may be any number of pockets, depending upon the tolerance and surface finish required. The cutter body rotates in the direction ofrotation 3. - Referring now to Figures 2 through 7, according to the invention, there is disclosed a sprocket cutter comprising a
cutter body 2 having a plurality of pockets 4 along its periphery 6 and a plurality ofwedge recesses 8 facing the periphery within each pocket. There is an array ofinserts 10 disposed within each of the pockets, each of the inserts having acutting portion 12. There is also a plurality ofwedges 14 equal in number to the number ofinserts 10 andwedge recesses 8. Each of thewedges 14 is interposed between each of theinserts 10 and each of the wedge recesses 8 so that as each of the wedges is moved inwardly, as shown by arrow 16, into its corresponding wedge recess each of the inserts is securely clamped between its corresponding wedge and the pocket. Each of the inserts is positioned so that the cutting portion of each insert extends beyond the periphery of the cutter body. Each of the inserts cuts a segment of thesprocket contour 18 of the sprocket 19 as the cutter body rotates with adjacent segments of the sprocket contour being cut by inserts located in different pockets. - The array of inserts within each station is the sum total of the individual positions of each insert. As shown in Figure 5, the inserts are arrayed so as to form the shape of a sprocket contour. However, it is contemplated within the scope of this invention that the inserts may be arrayed to form any complex contour.
- Figure 7 shows a portion of the station of Figure 5. A station is the cutter body pocket with its accompanying hardware.
Inserts 10 eachcut segment 20 from thesprocket contour 18. Some other station with inserts 10' shown in dotted lines in Figure 7 would cut an adjacent segment 20' from thesprocket contour 18.Adjacent segments 20 and 20' would be cut by different stations which would not necessarily be adjacent. That is, the station that cuts segments 20' could be the one, but not necessarily so, that next follows the station that cutssegments 20. - There is a plurality of
cartridges 22 corresponding to the number of cutter body pockets 4 for insertion into each of the pockets. Each of the cartridges has aninsert receiving portion 24 and arear portion 26. The cartridges are interposed in each pocket between the array of inserts and the pocket so that each of the inserts abuts 28, said insert receiving portion, and is securely clamped thereon by thewedges 14. - The cartridge may be securely held in the cutter body as by fastening means 23. The wedges may be moved inwardly and tightened as by fastening means 15.
- Preferably, the insert receiving portion comprises a plurality of insert seating positions 30 equal in number to the number of
inserts 10 in the array of inserts. Each of the insert seating positions has a V-shapedsurface 32 for accurately receiving and locating each of the inserts. - Preferably, also, the insert receiving portion further comprises a
shim recess 34 andshim 36 located rearwardly in the rotational sense from each of the insert seating positions so that the bottom 38 of each of the inserts will abut the top 40 of each of theshims 36. - Preferably, each of the pockets has a pair of locating
surfaces 42 abutting with a pair of locatingsurfaces 44 of therear portion 26 of each of thecartridges 22. The pocket locating surfaces 42 and thecartridge locating surface 44 similarly converge toward the periphery of thecutter body 2. - It is most preferable that each of the wedges has a
flat bearing surface 46 for engagement with each of theinserts 10 and arounded surface 48 opposite the flat bearing surface for engagement with a similarly roundedsurface 50 of thewedge recess 8. - In the preferred embodiment, the wedges would firmly position the inserts against the cartridge, but it is within the scope of this invention to eliminate the cartridge and have the wedges securely clamp the inserts within the pocket itself. From a practical standpoint, it is desirable to make use of the cartridge so as to avoid expensive machining on the cutter body.
- It is preferable that each of the pockets has a
chip gash portion 52 forward in the rotational sense of the array of inserts. The radius of the cutter body is reduced at each of thechip gash portions 52. - It is most desirable to have a chip gash portion in that it allows movement of the cut chip away from the cutter body thereby preventing the washing away of the cutter body.
- It is most preferred that each of the inserts is round.
- As best seen in Figure 4, the inserts are slightly skewed so that their cutting portions are not parallel to the axis of
rotation 54 of the cutter body. It has been found that when the cutting portions of the inserts are at an angle to the axis of rotation, the possibility of chatter is eliminated. - According to the invention, there is a cutter cartridge, as a separate article of commerce, comprising an
insert receiving portion 24 and arear portion 26. Each insert receiving portion has a plurality of. insert seating positions 30, each of which has a V-shaped surface for accurately receiving and locating a cutting insert. - Preferably, the insert receiving portion further comprises a
shim recess 34 andshim 36 located rearwardly in the rotational sense from each of the insert seating positions. It is also preferable that therear portion 24 of the cartridge has a pair of locatingsurfaces 44 converging toward theinsert receiving portion 24 of the cartridge. - According to the invention, disclosed is a method of assembling a sprocket cutter of the type having a cutter body having a plurality of pockets and wedge recesses. It is also of the type having a plurality of cartridges equal in number to the number of pockets and having a rear portion, a plurality of insert seating positions and shim recesses, both equal in number to the number of wedge recesses. The sprocket cutter is further of the type having a plurality of wedges equal in number to the number of wedge recesses. The method comprises inserting a
cartridge 22 into a pocket 4 of thecutter body 2 and causing the two locatingsurfaces 44 on therear portion 26 of the cartridge to abut two similar locating surfaces 42 in the pocket, each of the two locating surfaces converging toward the periphery of the cutter body, then locating a shim into each shim recess of the cartridge such that the shim protrudes slightly above the shim recess. The method further comprises placing an insert into each insert seating position 30 and on top of eachshim 36 and locating each insert with respect to a V-shaped locatingsurface 32 at the rear of each insert seating position. A further step is interposing awedge 14 between each insert and eachwedge recess 8 such that upon moving each wedge inwardly as shown by arrow 16, each insert will be securely clamped. The method is completed by repeating each step a number of times equal to the number of pockets in the cutter body. - Modifications may be made within the scope of the appended claims.
